6:50 a.m. update: Serious crash closes lane on Hwy. 52

What looks to be a serious crash has the right lane of southbound Hwy. 52 at Butler Avenue in West St. Paul. Lots of emergency vehicles are on the scene. Look for a minor slow down on the northbound side as the gawker effect kicks in.

Ramps can be slick. Just ask the motorist who slid off the ramp from County Road 11 to northbound I-35E in Apple Valley. We had one earlier up in Maple Grove.

A crash is now blocking the left lane of southbound 94 at Olson Hwy. Look for things to plug up quickly heading into the Lowry Hill Tunnel.

In addition to the third straight weekend closure of Interstate 94 in downtown Minneapolis, MnDOT will demolish the flyover bridge from northbound Interstate 35W to westbound Interstate 94. It will be closed until 2021.

The Minnesota Department of Transportation is reminding anglers heading to this weekend's fishing opener to plan ahead and leave plenty of time to get to their destination. The advice holds true for motorists traveling in downtown Minneapolis where two freeways will be closed.

The Minnesota Department of Transportation will shut the freeway down between Interstates 394 and 35W for the next three weekends to allow crews refurbish the Irene Hixon Whitney pedestrian bridge spanning I-94 and connecting the Minneapolis Sculpture Garden and Loring Park.
